PACKAGE SUPPORT OR HOLDER FOR INDEF INITE LENGTH MATERIAL Filed Jan. 9,195a 2 Sheets-Sheet 2 INVENTOR BY w fim ATTORNEYS United States PatentPACKAGE'SUPPORTOR HOLDER FOR INDEFINITE LENGTH MATERIAL Fred G. Parrott,Gastonia, NC. Application January-9, 1956, Serial No. 557,999 claims.-or; 242-130 This invention relates to a package support or holderatidfmore particularly; to a yarn package support or holderforsupportinga package of yarn while' the yarn thereon is being unwoundas ina'winding operation.

Heretofore; packages of yarn such as bobbins of yarn havebeen supportedon a spindle or nailwhile the yarn on the'pa'ck'ag'e is beingunwound'therefrom. Such supports; although efie'c'tive. to prevent thebobbin from falling on the floor, do not support the bobbin in such amanner-as to prevent the same from floppingaround while the yarnis'being taken therefrom. It has been observed that the movement of theyarn package or the flopping about'of the-same during the unwinding ofthe yarn there from causes entanglements in the yarn by the yarnsluifin'go'if or being withdrawn several convolutions atonce whichgreatly interfereswith the winding operation. It has also been observedthat the greater the difierence in diameter between the inside diameterof the yarn package and the-diameter of the package support,"the greaterthe diflicult'ies in evenly unwinding the yarn from the package sincethe amplitude or movement of the yarn package on the support is greaterwhich increases the entanglement and unevenness of the yarn being woundtherefrom.

his a primary object of this invention to overcome the above-mentioneddifiiculties of supporting a package of yarn when the yarn on the sameis being unwound in-a winding operation by providing a yarn packagesupport comprising a plurality of mating segments which: are sodimensioned as to selectively and frictionallyreceive various sizepackages of yarn thereon to'maintain-the package in an immovable uprightposition at alltimes.

It is a more specific objector the invention. to provide a yarnpackagesupport-or holder wherein: the same coinprises a plurality of matingsegments, each' segment adaptedto support at least one size of yarnpackage and wherein" the segments are telescopically arranged and-eachof the segments are adapted to be selectively removed to change-over theyarn" package support or holder to receive various size' packages of'yarn.

It is a further object of the invention to provide a yarn packagesupport or holder for supporting a package of yarn' during a windingoperation which support or holder comprises a plurality oftelescopically mating annular segments with each of the segments beingprovided with sloping or tapered walls-to increase the frictionalengagement with a package of yarn and to facilitate the positioning of apackage of yarn thereon.

Some ofthe'objects of the invention having been stated, other objectswill appear as the description proceeds when taken in connection withthe accompanying drawings, in which-- I Figure 1 is a fragmentaryperspective view showing theyar n package support or holder supporting apackage of yarn while the yarn thereon is being unwound as on a textilewinder;

-Referring more specifically to. the drawings, reference numeral 10broadlyindicates the yarn package support or" holder, .a plurality ofwhich (only one is' shown in Figure l) are fixedly secured in'sp'ac'edrelation on a package holder supporting rail 11 of a textile windermachine. Apackage of yarn P is positioned on each of the holders ltlandthe yarn Y is unwound therefrom while being guided by eyelets 12 and 13positioned on an upper rail 14' to atravers ing guide 1 5 mounted onatraversing rod 16 which lays'the yarn Y in layers on a sp'ool'17 beingrotated" as by'frictional contact by a rotary drum 18'. The yarn Y beingunwound from the package P will bew'ithdrawn smoothly, free of anyentanglements hereto fore caused by the movement of'the yarn package,since the package is frictionally engaged by the yarn package support 10as more clearly seen in FiguresiS, 6and" 7 wherein various size yarnbobbins are shown'positioned on the support or holder.

Referring particularly to Figure 2, the yarn package support or holder10 comprises a stationarily positioned spindle 20 to which is secured asby a set screw 22' a frusto-conicallygshaped inner or small size yarnpackage support segment 21. The upper portion of the segment 21 hasformed integraltherewith another frusto-conically shaped portion 21b'toactas'a guide to facilitate thepositioning of a package of yarnonthe'se'gment 21; A flange 23 is formed integral with the segment 21and serves to receive thelower edge of the package of yarn or bobbinwhen the same is positioned thereon as shown in Figure 7. intermediatesupport segment broadly indicated at 24' is telescopically received bythe segment '21 and is secured in its proper position on the spindle 20"by a set screw 25 engaging the spindle as more clearly shown in Figure4'. A flange 26 is formed integral with the intermediate support segment24 and extends outwardly from the lower edge thereof to provide a'seatfor an inter mediate size bobbin such. as bobbin B" as shown 'in Figure6. It will also be observed in Fi ure 6 that the flange 26 rests on theflange 23 of theinner segment '21. The intermediate support 24' isadapted to selectively carry three different size bobbins thereon andto" accomplish' this purpose, wall portions" 30, 31 and 32 are"provided. As will be observed in Figure 2, these wall portions are ofvarious size diameters to frictionall y engage three diiferent sizebobbins or yarn packages. The walls 30, 31 and 32 are slo'ped or taperedupwardly to facilitate the inserting ofa yarn package or bobbin thereon.Shoulder portions 33 and 34 define the upper and lower limits of thewall section 31 and alsodefine the upper and lower'limits of the wallsections 30' and 32; respectively; The shoulders 33, 34 also act asseats or stops for the yarn packages frictionally' engaging the wallportions 31', 32, respectively, in a similar manner as the flange 26acts as a stop or seat for y'a'rn' packages positibnedon wall 30. ITelescopically received by the intermediate support segment 24is theouteror large size supportse'grnent 35 which is secured to theintermediate segment 24 by a set screw 36 penetrating a threaded bore oraperture 37 (Figure 2) provided in the wall 30 of the segment 24.

The large size segment 35 is provided with a flange 38 along its loweredge which flange rests on the flange 26 of the intermediate segment 24as clearly shown in Figure 3. The upperedge of the large size segment 35'istapered or sloped as at 39 to facilitate the inserting of a yarnpackage thereon. The wall or body portion of the holder 35 is similarlytapered as the other segments 24 and 21 to increase the frictionalengagement'with a yarn package positioned thereon to prevent the samefrom flopping about when yarn is being unwound therefrom.

In Figure 5 is illustrated the yarn package support with the outersegment 35 frictionally engaging and maintaining a large size bobbin Bin upright position while yarn (not shown) is unwound from the same. InFigure-6 the large support segment 35 has been removed and the segment24 is shown as supporting an intermediate size bobbin B" in uprightposition while yarn (not shown) is being unwound from the same during awinding operation. In Figure 7 the holder device is shown with the outeror large size segment 35 and the intermediate size segment 24 removedand the inner or small segment supporting a small size bobbin B inupright position while yarn (not shown) is being unwound from the same.Although only three sizes of bobbins are illustrated in the drawings,the intermediate segment 24 is shaped to support two other sizes ofbobbins in addisaid segments being provided with tapered wall portionsto facilitate the positioning of a package of yarn thereon and toincrease the frictional engagement with the package of yarn.

2. A support for a package of yarn for maintaining the package of yarnin an immovable condition while the yarn is being withdrawn from thesame during a winding operation comprising a spindle, an inner yarnpackage receiving segment secured to said spindle, an intermediate yarnpackage receiving segment secured to said spindle, said intermediatesegment surrounding the major portion of said inner segment and restingthereon, an outer yarn package supporting segment secured to saidintermediate segment and surrounding the lower portion of saidintermediate segment, and each 'of said segments provided with taperedwall portions to facilitate the positioning of a package of yarn thereonand to increase the frictional tion to the bobbin B" shown in Figure 6,which bobbins I would be frictionally engaged by the wall portions 31 or32. Although the drawings do not show a bobbin smaller than bobbin B' asbeing held in an upright position by the bobbin holder, it is, ofcourse, apparent that a bobbin having an internal diameter substantiallythe same as the diameter of the spindle 20 may be positioned thereon.

Although the invention has been described as particularly adaptable forsupporting a package of yarn during the unwinding of the yarn therefromin a winding operation, it is to be distinctly understood that theinvention is not restricted thereto but may be practiced in any type ofoperation for supporting any type of package containing an indefinitelength of material such as wire, electrical conductors, etc., as well asyarn.

Accordingly, there has been provided a holder or support for a packageof yarn for maintaining the package of yarn in an upright position whileyarn is being removed therefrom during a winding operation and whereinthe holder frictionally engages the package of yarn to prevent the samefrom flopping about or moving to permit the yarn to be withdrawn fromthe same in a smooth manner without interfering with the windingoperation.

In the drawings and specification there has been set forth a preferredembodiment of the invention and, although specific terms are employed,they are used in a generic and descriptive sense only and not forpurposes of limitation, the scope of the invention being defined in theclaims.
